Answer:
Explanation:
In case of diffraction , angular width of central maxima =2 λ/d
λ is wave length of light and d is slit width
In case of interference , angular width of each fringe 
= λ /D 
D is distance between two slits
No of interference fringe in central diffraction fringe 
=2 λ/d x D/λ = 2 x D /d = 2 x .24/.03 = 16.
 
        
             
        
        
        
There is no theoretical OR observational evidence for that statement.
        
             
        
        
        
Choices 'a', 'c', and 'd' are true.
In choice 'b', I'm not sure what it means when it says that masses 
are 'balanced'.  To me, masses are only balanced when they're on
a see-saw, or on opposite ends of a rope that goes over a pulley.
Maybe the statement means that the mass of the nucleus and the 
mass of the electron cloud are equal.  This is way false.  It takes 
more than 1,800 electrons to make the mass of ONE proton or 
neutron, and the most complex atom in nature only has 92 electrons 
in it.  So there's no way that the masses of the nucleus and the electrons
in one atom could ever be anywhere near equal.
        
             
        
        
        
Answer:
a) When moving towards a high pressure center the pressure values increase in the equipment
b) This area is called high prison since the weight of the atmosphere on top is maximum
Explanation:
A) A high atmospheric pressure system is an area where the pressure is increasing the maximum value is close to 107 Kpa, the other side as low pressure can have small values 85.5 kPa.
When moving towards a high pressure center the pressure values increase in the equipment
 B) This area is called high prison since the weight of the atmosphere on top is maximum
in general they are areas of good weather
 
        
             
        
        
        
Answer:
Blue Lighting
Explanation:
In order to make red look black, you must use blue light. The blue would be absorbed and there would be no red light to reflect.
